I'm betting 303 days of my life on AI agents.

I've been coding for 20 years. PHP, Python, React. Solo. No team, no VC.

Then AI started doing what I do.

I panicked for a while. Then one thought changed everything:

"What if I just command the AI instead?"

That's all it took.

Starting today, I'm running a 303-day public experiment.

The bet: build ₩20,000,000/month (~$14,000 MRR) using only AI agents. 4 revenue streams. Everything public.

The 4 axes

• NaholroAI — agent-built solutions. No teaching.
• ATOZAI — agent marketplace + revenue hub (Korea)
• MrBAN Global — this site. English build-in-public.
• Investment Arena — two AIs battle in public. Paper trading now. Real money (₩10M total) starts May 30. Every decision public.

The rules

• Every number, every week. Even $0. Even negative.
• Every agent decision published. Why it bought. Why it was wrong.
• Every failure documented. Dead agents get obituaries.

Securities firms show results. I show thinking.

That's the only difference. That's the bet.

D-303 starts now.
